my 90 seems to be stuck in difflock giving me wind up when driving. it has been off the road for 5 months during which i fitted a disco transfer box, but being a NA engine with bigger tyres the forum doubted that it would cope, so I put my old one back.
just as i completed the work whick was bulkhead, A posts and footwells, i developed a leak in the rear axle,
i got a replacement thro 'SLROC and thought that was causing it but yesterday, I swopped the diff and drive shafts over to the original and still have wind up.
could it be stuck due to non use ?
any advice would be gratefully received
